Fluxes of gases and particles above a deciduous forest in wintertime

Eddy-correlation measurements of the vertical fluxes of ozone, CO sub(2) , fine particles with a diameter similar to 0.1 mu m, particulate sulfur, momentum, heat, and water vapor were taken above a tall, leafless, deciduous forest in wintertime. During the experimental period of one week, ozone depo...

Description
Summary:Eddy-correlation measurements of the vertical fluxes of ozone, CO sub(2) , fine particles with a diameter similar to 0.1 mu m, particulate sulfur, momentum, heat, and water vapor were taken above a tall, leafless, deciduous forest in wintertime. During the experimental period of one week, ozone deposition velocities varied from similar to 0.1 cm sec super(-) super(1) at night to more than 0.4 cm sec super(-) super(1) during the daytime, with the largest variations associated primarily with changes in solar irradiation. Most of the ozone removal took place in the upper canopy. CO sub(2) fluxes were directed upward because of respiration and exhibited a strong dependence upon air temperature and solar heating. The fluxes were approximately zero at air temperatures
